Quick take

Type III sink-tip fly line with 10-foot sinking section for streamer fishing.

The Scientific Anglers Frequency Sink Tip is a 5-weight fly line with a 10-foot Type III sinking tip on a mid-length head. It is built for streamers and wet flies in moving water, for trout, steelhead, salmon and smallmouth bass. Its Optic Yellow/Green color is the one to know when you spool it up.

Best for

  • Streamer presentations in moving water
  • Trout and steelhead in rivers and fast flows
  • Fishing flies below the surface while maintaining control

Skip if

  • You need a floating line for dry flies or nymphs
  • You fish slack, slow current where surface control is less critical

Strengths

  • Type III tip sinks quickly without over-loading lighter rods
  • Ten-foot sinking length fishes streamer depth effectively
  • Mid-length floating belly enhances casting control

Trade-offs

  • Sink-tip requires practice to detect strikes compared to floating lines
  • Transitions between sinking tip and floating belly can cause tangles
  • Best suited to moving water; less effective in ponds or lakes
